Walland Marsh is a part of Romney Marsh, mostly in Kent with part in East Sussex. The name means wall-land: its north-eastern border, separating it from the rest of Romney Marsh, is the Rhee Wall.
The Rhee Wall is 7.5 miles long and runs from Appledore, through Brenzett and Old Romney to New Romney; it consists of two parallel earth banks, from 50 to 100 metres apart, the ground between being raised above the marsh on either side. It was built in the 13th century, as a watercourse to wash away silt from the harbour at New Romney. The plan eventually failed; the Rhee Wall has not contained water since medieval times.
Walland Marsh is bordered in the south-east by Lydd (beyond which is Denge Marsh) and in the south-west by Rye. The villages of Fairfield, Brookland and East Guldeford are within the region.
The marsh was turned into productive farm land in past centuries. The land of Walland Marsh was reclaimed mostly from the 13th to 15th century, later than that of Romney Marsh to the north-east. The reclamation was done in stages by creating innings: an embankment was built round an area of marsh, which would drain at low tide.
Walland is an unincorporated community and census-designated place (CDP) in Blount County, Tennessee, in the Southeastern United States. Its population was 259 as of the 2010 census. Walland is the site of a post office and is the place name associated with zip code 37886, which covers an area beyond the Walland community.
Walland is situated in Miller's Cove, an enclosed valley in the northwestern foothills of the Great Smoky Mountains. Miller's Cove (spelled "Miller Cove" on USGS maps) is walled off to the north by Chilhowee Mountain, a low ridge stretching for 35 miles between the Little Tennessee River to the west and the Little Pigeon River watershed to the east. Hurricane Mountain to the southwest and Bates Mountain to the southeast divide Miller's Cove from the much larger Tuckaleechee Cove at the base of the Smokies.
Little River, which flows down from its source on the northern slopes of Clingmans Dome, splits Miller's Cove into eastern and western sections en route to flatlands of northern Blount County. The river's valley, which divides Hurricane and Bates Mountain and slices a large gap through Chilhowee Mountain, has long provided a convenient bottomland for trails and roads linking the coves of the northern Smokies. Today, it is traversed by U.S. Route 321, which connects Interstate 40 to the Great Smoky Mountains National Park. The park boundary is about 15 miles south of Walland.
